A Stand Alone Single Axis Offline PV Tracker Using Low Cost CMOS Circuitryfree download
tracking systems. Ali Al-Mohamad designed a Sun-tracking system, whereby the
movement of a photovoltaic module was controlled to follow the Sun's radiation using
a programmable logic-controller (PLC) unit. . Mohanad
Switching mode power-supply for the Sun-follower system Controls the tracking system movement:
the logic consequences for the controlling process are illustrated in Fig Monitors the PLC inputs
and outputs: the main duty of this subroutine is to copy the status of the PLC inputs
In the present study, the azimuth and solar altitude angles of the sun were calculated for a
period of 1 year at 37.6° latitude in the Northern hemisphere, where Turkey is located, and
according to these angles, an electromechanical system which tracks the sun on both
of authors used a closed loop method of control to design sun tracking systems [8], [10], [11] and
[12]. In this work, the designs for two axes and one axis tracking systems were performed using
an open loop method of control based upon programmable logic controllers (PLC).
A review of
principle and sun-tracking methods for maximizing solar systems output. In this paper different
types of sun-tracking systems are reviewed and their cons and pros are discussed.
